APPARATUS FOR PULLING PLIES OR THE LIKE.

Specification of Letters Patent. Patented Mar. 22, 1921.

Application filed April 28, 1919. Serial No. 293,273.

To all whom it may concern:

Be it known that we, JAMES A. PURvIs and HERBERT A. SESSIONS, citizensof the United States, and residents of Traverse City, in the county ofGrand Traverse and State of Michi an, have invented certain new anduseful mprovements in Apparatus for Pulling Plies or the like, of whichthe following is a specification.

Our invention is an improvement in apparatus for pulling 'plies or thelike, and has for its object to. rovide a machine of the characterspecifie especially designedfor pulling plies of fabric from old pneu-.

section of the I tion, and in this frame there is arran ed a wheel ordrum 2, said wheel or drum eing secured to a shaft 3.

The ends of the shaft 3 are journaled in hooks l in the arms 5 of a yokeconsisting of the said arms and a body 6. This yoke is connected to theend of the frame by a chain 7, one end of the chain engaging the body ofthe yoke, which is V-shaped as shown, 35

and the other is engaged with a bracket 8 on the frame. a

The bracket consists of a plate which is secured to the frame at thecenter of one end, and two upstanding lugs on the plate, said lugs beingspaced apart far enough to receive a link of the chain, when the planeof the link .is vertical. Thus the drum and the shaft may be adjustedlongitudinally of i and it is obvious that when the crank shaft isrotated, the drum 9 will also .be rotated,

but in the-opposite direction to the rotation of the crank shaft.

The drum has on its periphery a longitu- I dinally extending-slot 17,and this slot is adapted to receive a holding bar 18 pivoted on one endto an arm 19 extending radially from the shaft 10, and having at theother a bearing for enga ing a reduced threaded stem 20 .on a radial arm21 at the opposite end of the drum. A nut 22 engages the stem to preventdisplacement of the bar.

In operation, the oldtire from which it is desired to remove a reateror-less number of fabric plies, has rst the bead strip removed, afterwhich the tire is placed on the wheel or drum 2, in the manner shown inFig. 1 started in any suitable or desired manner.

The ends of these plies are then engaged within the groove 17, and arelocked in the groove by the locking bar. When now the drum 9 is turnedby means of the crank, it will be obvious that the plies will be woundupon the said drum, and will be stripped As the plies are stripped thetire which acts as a belt will rotate the wheel '2, in the oppositedirection to the rotation of the drum 9.

As is known, reliners thus obtained are preferable, since in themakmg ofthe tire,

the .fabric is vulcanized under great pressure, and will .not separate.In the usual reliners the fabric is merely cemented. Stripping the tiresmanually is a slow, difficult and costly process. 'Wlth the improvedmachine a tire may be stripped in a very short space of time and withbut little labor. By means of the chain 7 the holding drum 2 may bemoved toward and from the stripping drum, to provide for tiresofdilferent diameter. Referring to Fig; 3 it will be noticed that thespiders 11 and the radial arms 19Jand 21 are keyed to the shaft 10.

We claim:

1. A machine of the character specified, comprising a supporting frame,a drum journaled thereon and having a longitudinally extending groove inits periphery, a locking bar for engaging the groove to clamp the fabricmaterial therein, means for rotating the drum, and means for supportingthe tire to be stripped during the stripping, said supporting meanscomprising a drum for engagement by the tire, and means for supportingthe drum for rotation on the and the desired number of plies is from thetire, which is held by the wheel 2.

frame, said supporting means being adjust- 2; A machine of the characterspecified, comprising a supporting frame, a drum journaled thereon andhaving a longitudinally extending groove in its periphery, a locking barfor engaging the groove to clamp the fabric material therein, means forrotating the drum, and means for supporting the tire to be strippedduring the stripping, said supportim means comprising a drum forengagement by the tire, and means for supporting the drum for rotationon the frame.

3. A machine of the character specified, comprising a supporting frame,a drum journaled thereon and having a longitudinally extending groove inits periphery, a locking bar for engaging the groove to clamp the fabricmaterial therein, means for rotating the drum, and means for supportingthe tire to be stripped during the stripping, the looking bar having apivotal connection'at one end with the drum, and a detachable connectionat the other end.

4. A machine of the character specified, comprising a supporting frame,a drum 'jour-- naled thereon and having a longitudinally extendinggroove in its periphery, a locking bar for engaging the groove to clampthe fabric material therein, means for rotating the drum, and means forsupporting the tire to be stripped during the stripping.

5. A machine of the character described comprising a frame, means forengaging plies of the tire and pulling the same thererom, a rotatabledrum for supporting the tire during the pulling operation, and means forvarying the position of the drum to accommodate various size tiresincluding a yoke having side arms slidably arranged on said frame saidarms being provided with hooked ends constituting journals for saiddrum, a chain having one end connected to said yoke, and means fixed tothe frame and selectively engageable with the links of the chain, as andfor the purpose set forth.
